CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 274,107, dated March.20, 1883. A plication. filed October 26,1882. (No model.)

. tain new and useful Improvement in Car- Doors, of which "the followingis a specification, reference being had to the accompanying drawings. gY

My invention relates more particularly to that class of doors which isused in cars when carrying grain, being required independently of theordinary door, which is all that is necessary in carrying ordinaryfreight. There is generally used for this purpose a temporary door,which usually answers the purpose for but a single trip.

My invention consists in the novel construction of the hinge and themethod of hanging the door.

The drawings represent the inside of a car, Figure 1 showing the doorclosed, and Fig. 2 showing the position of the door as folded back andsecured when not in use, like letters indicating like parts in the twofigures.

The door is constructed a little less than half the height of the car,and is hinged to the door post or support at one upper corner only. Thehinge, as constructed, forms a ball-andsocket joint. It consists of aball, A, with a shank,a, by means of which it is secured to the doors,and two retaining-sockets, B B, each consisting of a lug containing aconcave cavity and provided with a shank adjusted to clutch and retainthe ball A, and secured to the door post or support by means of theshanks. The shank of one of the sockets may, if desired, be providedwith slots, through whichthe retaining screws or bolts pass, so that thesocket may be adjusted to regulate the friction of the joint or take upits wear. Stops or brackets 0 care secured on the floor of thecar toretain the bottom of the door when'closed. Through the operation of thishinge the door may be folded back against the side of the car in theposition shown by the dotted lines in Fig. 2, and turned up in thepositionin which the door is shown in that figure,where it may besecured by the catch 01. As freight-cars are ordinarily constructed thedoor in this position lies closely against the side of thecar, and

thus offers no obstruction to the available space of the interior. Thehinge permits the door to be brought to any desired position, which factaffords many advantages. Being easily raised to the position shown bythe dotted lines in Fig. 1, it allows the dumping of the grain, avoidingthe difficulty of opening or removing the door when the grain ispressing against it, encountered in other forms of doors.

It is apparent that the hinge might be applied by securing the ball uponthe jamb-post and the retaining-sockets upon the door, and that thehinge might be applied to many other uses than the one particularlymentioned, in all which cases my invention would be embodied.

Havingthus described my invention, what I claim as new, and desire tosecure by Letters .Patent, is-

A hinge consisting of a ball, A, provided with a shank for securing thesame to the door orjamb, in combination with the two retaining-sockets BB.
